Abstract

Atomic mechanisms of elastic-stress relaxation in heteroepitaxial structures are investigated by computer simulation. A 2D model of a heteroepitaxial structure with an empirical interatomic potential is considered. Advanced methods of saddle-point search in a multidimensional space are used to identify main mechanisms of structural change involving the formation of a structural imperfection, and to estimate energy characteristics of the processes.
